Temperature Effect on the Radioluminescence of Differently Doped Silica-Based Optical Fibers / Kerboub, Nourdine (CERN ; CNES, Toulouse ; Lab. Hubert Curien, St. Etienne) ; Di Francesca, Diego (CERN) ; Morana, Adriana (Lab. Hubert Curien, St. Etienne) ; Hamzaoui, Hicham El (PhLAM, Villeneuve d'Ascq) ; Ouerdane, Youcef (Lab.

Hubert Curien, St. Etienne) ; Capoen, Bruno (PhLAM, Villeneuve d'Ascq) et al.
We evaluate the temperature effect on the X-ray radiation-induced luminescence (RIL) of differently doped silica fibers obtained via the sol-gel route. Previous investigations showed that these optical materials exhibit interesting dosimetry properties, such as very good detection capabilities and linear response over a large range of dose rate.

Measurement of the CKM angle $\gamma$ in $B^\pm\to DK(892)^{*\pm}$ decays / LHCb Collaboration
Measurements of $CP$ observables and the CKM angle $\gamma$ are performed in $B^{\pm} \to D K^*(892)^{\pm}$ decays, where $D$ represents a superposition of $D^0$ and $\overline{D}{}^0$ states, using the LHCb dataset collected during Run 1 (2011-2012) and Run 2 (2015-2018). [...]

Characterization of Radiophotoluminescence Dosimeters Under X-Ray Irradiation at High Doses / Ferrari, M (Lab. Hubert Curien, St. Etienne) ; Aguiar, Y Q (CERN) ; Hasan, A (Lab. Hubert Curien, St. Etienne) ; Alem, A K (Lab. Hubert Curien, St. Etienne) ; Alía, R García (CERN) ; Donzella, A (Brescia U.) ; Pagano, D (Brescia U.) ; Sostero, L (Brescia U.) ; Zenoni, A (Brescia U.) ; Girard, S (Lab. Hubert Curien, St. Etienne ; IUF, Paris)
A characterization of radiophotoluminescence (RPL) dosimeters at high doses of X-ray radiation for applications in high-radiation areas is presented. Commercial FD-7 silver-doped phosphate glasses (1.5$\times$ 8.5mm) in use at CERN for passive dosimetry are irradiated using commercial X-ray tubes. [...]

Optimizing time resolution and power consumption in a current-mode circuit for SiPMs / Manera, R (ICC, Barcelona U.) ; Gómez, S (Barcelona, Polytechnic U. ; ICC, Barcelona U.) ; Mariscal-Castilla, A (ICC, Barcelona U.) ; Mauricio, J (ICC, Barcelona U.) ; Ballabriga, R (CERN) ; Gascón, D (ICC, Barcelona U.)
Several applications that employ SiPMs require high time precision readout electronics. This work presents a study for the optimization of timing resolution of readout electronics for SiPMs focused on the effect of sensor area, transistor scaling and power consumption on electronic jitter. [...]

Radiological clearance of historical waste from particle accelerators / Svihrova, Lucie (CERN ; Prague, Tech. U.) ; Bauer, Kerstin (CERN) ; Bruno, Luca (CERN) ; Dumont, Gerald (CERN) ; Magistris, Matteo (CERN) ; Menaa, Nabil (CERN) ; Silari, Marco (CERN) ; Ulrici, Luisa (CERN)
This paper presents a detailed methodology for reclassifying radioactive material from particle accelerators as non-radioactive, drawing on experiences at CERN. During particle accelerator decommissioning, the waste is classified based on its radioactivity level where the very-low-level activity material is the potential clearance candidate. [...]

Ultra-Large Silicon Diode for Characterizing Low-Intensity Radiation Environments / Biłko, Kacper (CERN ; Jean Monnet U.) ; García Alía, Rubén (CERN) ; Girard, Sylvain (Jean Monnet U. ; IUF, Paris) ; Barbero, Mario Sacristan (CERN) ; Cecchetto, Matteo (CERN) ; Belanger-Champagne, Camille (TRIUMF) ; Brucoli, Matteo (CERN) ; Danzeca, Salvatore (CERN) ; Hands, Alex (CERN) ; Holgado, Pedro Martín (Seville U.) et al.
We present applications of a large commercial silicon diode (50 cm $^{2}\,\,\times 500\,\,{\mu }\text{m}$ ) for monitoring low-intensity radiation fields, together with benchmarks via Monte Carlo simulations. After energy calibration with monoenergetic proton and alpha beams in the 2–8-MeV range, we show that the detector is capable of measuring atmospheric radiation at the ground level, not only in terms of a total number of events but also through their energy deposition distribution.
